| 6 | ABOUT: |
| 7 | This is a minimal state graphical user interface single header toolkit |
| 8 | written in ANSI C and licensed under public domain. |
| 9 | It was designed as a simple embeddable user interface for application and does |
| 10 | not have any dependencies, a default renderbackend or OS window and input handling |
| 11 | but instead provides a very modular library approach by using simple input state |
| 12 | for input and draw commands describing primitive shapes as output. |
| 13 | So instead of providing a layered library that tries to abstract over a number |
| 14 | of platform and render backends it only focuses on the actual UI. |
| 15 | |
| 16 | VALUES: |
| 17 | - Graphical user interface toolkit |
| 18 | - Single header library |
| 19 | - Written in C89 (a.k.a. ANSI C or ISO C90) |
| 20 | - Small codebase (~17kLOC) |
| 21 | - Focus on portability, efficiency and simplicity |
| 22 | - No dependencies (not even the standard library if not wanted) |
| 23 | - Fully skinnable and customizable |
| 24 | - Low memory footprint with total memory control if needed or wanted |
| 25 | - UTF-8 support |
| 26 | - No global or hidden state |
| 27 | - Customizable library modules (you can compile and use only what you need) |
| 28 | - Optional font baker and vertex buffer output |
| 29 | |
| 30 | USAGE: |
| 31 | This library is self contained in one single header file and can be used either |
| 32 | in header only mode or in implementation mode. The header only mode is used |
| 33 | by default when included and allows including this header in other headers |
| 34 | and does not contain the actual implementation. |
| 35 | |
| 36 | The implementation mode requires to define the preprocessor macro |
| 37 | NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.: |
| 38 | |
| 39 | #define NK_IMPLEMENTATION |
| 40 | #include "nuklear.h" |
| 41 | |
| 42 | Also optionally define the symbols listed in the section "OPTIONAL DEFINES" |
| 43 | below in header and implementation mode if you want to use additional functionality |
| 44 | or need more control over the library. |
| 45 | IMPORTANT: Every time you include "nuklear.h" you have to define the same flags. |
| 46 | This is very important not doing it either leads to compiler errors |
| 47 | or even worse stack corruptions. |
| 48 | |
| 49 | FEATURES: |
| 50 | - Absolutely no platform dependend code |
| 51 | - Memory management control ranging from/to |
| 52 | - Ease of use by allocating everything from standard library |
| 53 | - Control every byte of memory inside the library |
| 54 | - Font handling control ranging from/to |
| 55 | - Use your own font implementation for everything |
| 56 | - Use this libraries internal font baking and handling API |
| 57 | - Drawing output control ranging from/to |
| 58 | - Simple shapes for more high level APIs which already have drawing capabilities |
| 59 | - Hardware accessible anti-aliased vertex buffer output |
| 60 | - Customizable colors and properties ranging from/to |
| 61 | - Simple changes to color by filling a simple color table |
| 62 | - Complete control with ability to use skinning to decorate widgets |
| 63 | - Bendable UI library with widget ranging from/to |
| 64 | - Basic widgets like buttons, checkboxes, slider, ... |
| 65 | - Advanced widget like abstract comboboxes, contextual menus,... |
| 66 | - Compile time configuration to only compile what you need |
| 67 | - Subset which can be used if you do not want to link or use the standard library |
| 68 | - Can be easily modified to only update on user input instead of frame updates |
| 69 | |
| 70 | OPTIONAL DEFINES: |
| 71 | NK_PRIVATE |
| 72 | If defined declares all functions as static, so they can only be accessed |
| 73 | inside the file that contains the implementation |
| 74 | |
| 75 | NK_INCLUDE_FIXED_TYPES |
| 76 | If defined it will include header <stdint.h> for fixed sized types |
| 77 | otherwise nuklear tries to select the correct type. If that fails it will |
| 78 | throw a compiler error and you have to select the correct types yourself. |
| 79 | <!> If used needs to be defined for implementation and header <!> |
| 80 | |
| 81 | NK_INCLUDE_DEFAULT_ALLOCATOR |
| 82 | if defined it will include header <stdlib.h> and provide additional functions |
| 83 | to use this library without caring for memory allocation control and therefore |
| 84 | ease memory management. |
| 85 | <!> Adds the standard library with malloc and free so don't define if you |
| 86 | don't want to link to the standard library <!> |
| 87 | <!> If used needs to be defined for implementation and header <!> |
| 88 | |
| 89 | NK_INCLUDE_STANDARD_IO |
| 90 | if defined it will include header <stdio.h> and provide |
| 91 | additional functions depending on file loading. |
| 92 | <!> Adds the standard library with fopen, fclose,... so don't define this |
| 93 | if you don't want to link to the standard library <!> |
| 94 | <!> If used needs to be defined for implementation and header <!> |
| 95 | |
| 96 | NK_INCLUDE_STANDARD_VARARGS |
| 97 | if defined it will include header <stdarg.h> and provide |
| 98 | additional functions depending on variable arguments |
| 99 | <!> Adds the standard library with va_list and so don't define this if |
| 100 | you don't want to link to the standard library<!> |
| 101 | <!> If used needs to be defined for implementation and header <!> |
| 102 | |
| 103 | NK_INCLUDE_VERTEX_BUFFER_OUTPUT |
| 104 | Defining this adds a vertex draw command list backend to this |
| 105 | library, which allows you to convert queue commands into vertex draw commands. |
| 106 | This is mainly if you need a hardware accessible format for OpenGL, DirectX, |
| 107 | Vulkan, Metal,... |
| 108 | <!> If used needs to be defined for implementation and header <!> |
| 109 | |
| 110 | NK_INCLUDE_FONT_BAKING |
| 111 | Defining this adds the `stb_truetype` and `stb_rect_pack` implementation |
| 112 | to this library and provides font baking and rendering. |
| 113 | If you already have font handling or do not want to use this font handler |
| 114 | you don't have to define it. |
| 115 | <!> If used needs to be defined for implementation and header <!> |
| 116 | |
| 117 | NK_INCLUDE_DEFAULT_FONT |
| 118 | Defining this adds the default font: ProggyClean.ttf into this library |
| 119 | which can be loaded into a font atlas and allows using this library without |
| 120 | having a truetype font |
| 121 | <!> Enabling this adds ~12kb to global stack memory <!> |
| 122 | <!> If used needs to be defined for implementation and header <!> |
| 123 | |
| 124 | NK_INCLUDE_COMMAND_USERDATA |
| 125 | Defining this adds a userdata pointer into each command. Can be useful for |
| 126 | example if you want to provide custom shaders depending on the used widget. |
| 127 | Can be combined with the style structures. |
| 128 | <!> If used needs to be defined for implementation and header <!> |
| 129 | |
| 130 | NK_BUTTON_TRIGGER_ON_RELEASE |
| 131 | Different platforms require button clicks occuring either on buttons being |
| 132 | pressed (up to down) or released (down to up). |
| 133 | By default this library will react on buttons being pressed, but if you |
| 134 | define this it will only trigger if a button is released. |
| 135 | <!> If used it is only required to be defined for the implementation part <!> |
| 136 | |
| 137 | NK_ZERO_COMMAND_MEMORY |
| 138 | Defining this will zero out memory for each drawing command added to a |
| 139 | drawing queue (inside nk_command_buffer_push). Zeroing command memory |
| 140 | is very useful for fast checking (using memcmp) if command buffers are |
| 141 | equal and avoid drawing frames when nothing on screen has changed since |
| 142 | previous frame. |
| 143 | |
| 144 | NK_ASSERT |
| 145 | If you don't define this, nuklear will use <assert.h> with assert(). |
| 146 | <!> Adds the standard library so define to nothing of not wanted <!> |
| 147 | <!> If used needs to be defined for implementation and header <!> |
| 148 | |
| 149 | NK_BUFFER_DEFAULT_INITIAL_SIZE |
| 150 | Initial buffer size allocated by all buffers while using the default allocator |
| 151 | functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't |
| 152 | want to allocate the default 4k memory then redefine it. |
| 153 | <!> If used needs to be defined for implementation and header <!> |
| 154 | |
| 155 | NK_MAX_NUMBER_BUFFER |
| 156 | Maximum buffer size for the conversion buffer between float and string |
| 157 | Under normal circumstances this should be more than sufficient. |
| 158 | <!> If used needs to be defined for implementation and header <!> |
| 159 | |
| 160 | NK_INPUT_MAX |
| 161 | Defines the max number of bytes which can be added as text input in one frame. |
| 162 | Under normal circumstances this should be more than sufficient. |
| 163 | <!> If used it is only required to be defined for the implementation part <!> |
| 164 | |
| 165 | NK_MEMSET |
| 166 | You can define this to 'memset' or your own memset implementation |
| 167 | replacement. If not nuklear will use its own version. |
| 168 | <!> If used it is only required to be defined for the implementation part <!> |
| 169 | |
| 170 | NK_MEMCPY |
| 171 | You can define this to 'memcpy' or your own memcpy implementation |
| 172 | replacement. If not nuklear will use its own version. |
| 173 | <!> If used it is only required to be defined for the implementation part <!> |
| 174 | |
| 175 | NK_SQRT |
| 176 | You can define this to 'sqrt' or your own sqrt implementation |
| 177 | replacement. If not nuklear will use its own slow and not highly |
| 178 | accurate version. |
| 179 | <!> If used it is only required to be defined for the implementation part <!> |
| 180 | |
| 181 | NK_SIN |
| 182 | You can define this to 'sinf' or your own sine implementation |
| 183 | replacement. If not nuklear will use its own approximation implementation. |
| 184 | <!> If used it is only required to be defined for the implementation part <!> |
| 185 | |
| 186 | NK_COS |
| 187 | You can define this to 'cosf' or your own cosine implementation |
| 188 | replacement. If not nuklear will use its own approximation implementation. |
| 189 | <!> If used it is only required to be defined for the implementation part <!> |
| 190 | |
| 191 | NK_STRTOD |
| 192 | You can define this to `strtod` or your own string to double conversion |
| 193 | implementation replacement. If not defined nuklear will use its own |
| 194 | imprecise and possibly unsafe version (does not handle nan or infinity!). |
| 195 | <!> If used it is only required to be defined for the implementation part <!> |
| 196 | |
| 197 | NK_DTOA |
| 198 | You can define this to `dtoa` or your own double to string conversion |
| 199 | implementation replacement. If not defined nuklear will use its own |
| 200 | imprecise and possibly unsafe version (does not handle nan or infinity!). |
| 201 | <!> If used it is only required to be defined for the implementation part <!> |
| 202 | |
| 203 | NK_VSNPRINTF |
| 204 | If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` |
| 205 | and want to be safe define this to `vsnprintf` on compilers supporting |
| 206 | later versions of C or C++. By default nuklear will check for your stdlib version |
| 207 | in C as well as compiler version in C++. if `vsnprintf` is available |
| 208 | it will define it to `vsnprintf` directly. If not defined and if you have |
| 209 | older versions of C or C++ it will be defined to `vsprintf` which is unsafe. |
| 210 | <!> If used it is only required to be defined for the implementation part <!> |
| 211 | |
| 212 | NK_BYTE |
| 213 | NK_INT16 |
| 214 | NK_UINT16 |
| 215 | NK_INT32 |
| 216 | NK_UINT32 |
| 217 | NK_SIZE_TYPE |
| 218 | NK_POINTER_TYPE |
| 219 | If you compile without NK_USE_FIXED_TYPE then a number of standard types |
| 220 | will be selected and compile time validated. If they are incorrect you can |
| 221 | define the correct types by overloading these type defines. |

| 768 | /* This library was designed to be render backend agnostic so it does |
| 769 | * not draw anything to screen directly. Instead all drawn shapes, widgets |
| 770 | * are made of, are buffered into memory and make up a command queue. |
| 771 | * Each frame therefore fills the command buffer with draw commands |
| 772 | * that then need to be executed by the user and his own render backend. |
| 773 | * After that the command buffer needs to be cleared and a new frame can be |
| 774 | * started. It is probably important to note that the command buffer is the main |
| 775 | * drawing API and the optional vertex buffer API only takes this format and |
| 776 | * converts it into a hardware accessible format. |
| 777 | * |
| 778 | * Usage |
| 779 | * ------------------- |
| 780 | * To draw all draw commands accumulated over a frame you need your own render |
| 781 | * backend able to draw a number of 2D primitives. This includes at least |
| 782 | * filled and stroked rectangles, circles, text, lines, triangles and scissors. |
| 783 | * As soon as this criterion is met you can iterate over each draw command |
| 784 | * and execute each draw command in a interpreter like fashion: |
| 785 | * |
| 786 | * const struct nk_command *cmd = 0; |
| 787 | * nk_foreach(cmd, &ctx) { |
| 788 | * case NK_COMMAND_LINE: |

| 792 | * your_draw_rect_function(...) |
| 793 | * break; |
| 794 | * case ...: |
| 795 | * [...] |
| 796 | * } |
| 797 | * |
| 798 | * In program flow context draw commands need to be executed after input has been |
| 799 | * gathered and the complete UI with windows and their contained widgets have |
| 800 | * been executed and before calling `nk_clear` which frees all previously |
| 801 | * allocated draw commands. |
| 802 | * |
| 803 | * struct nk_context ctx; |
| 804 | * nk_init_xxx(&ctx, ...); |
| 805 | * while (1) { |
| 806 | * Event evt; |
| 807 | * nk_input_begin(&ctx); |

| 809 | * if (evt.type == MOUSE_MOVE) |
| 810 | * nk_input_motion(&ctx, evt.motion.x, evt.motion.y); |
| 811 | * else if (evt.type == [...]) { |
| 812 | * [...] |
| 813 | * } |
| 814 | * } |
| 815 | * nk_input_end(&ctx); |
| 816 | * |
| 817 | * [...] |
| 818 | * |
| 819 | * const struct nk_command *cmd = 0; |
| 820 | * nk_foreach(cmd, &ctx) { |
| 821 | * case NK_COMMAND_LINE: |
| 822 | * your_draw_line_function(...) |
| 823 | * break; |
| 824 | * case NK_COMMAND_RECT |

| 833 | * |
| 834 | * While using draw commands makes sense for higher abstracted platforms like |
| 835 | * X11 and Win32 or drawing libraries it is often desirable to use graphics |
| 836 | * hardware directly. Therefore it is possible to just define |
| 837 | * `NK_INCLUDE_VERTEX_BUFFER_OUTPUT` which includes optional vertex output. |
| 838 | * To access the vertex output you first have to convert all draw commands into |
| 839 | * vertexes by calling `nk_convert` which takes in your prefered vertex format. |
| 840 | * After successfully converting all draw commands just iterate over and execute all |

| 971 | * WINDOW |
| 972 | * |
| 973 | * ============================================================================= |
| 974 | * Windows are the main persistent state used inside nuklear and are life time |
| 975 | * controlled by simply "retouching" (i.e. calling) each window each frame. |
| 976 | * All widgets inside nuklear can only be added inside function pair `nk_begin_xxx` |
| 977 | * and `nk_end`. Calling any widgets outside these two functions will result in an |
| 978 | * assert in debug or no state change in release mode. |
| 979 | * |
| 980 | * Each window holds frame persistent state like position, size, flags, state tables, |
| 981 | * and some garbage collected internal persistent widget state. Each window |
| 982 | * is linked into a window stack list which determines the drawing and overlapping |
| 983 | * order. The topmost window thereby is the currently active window. |
| 984 | * |
| 985 | * To change window position inside the stack occurs either automatically by |
| 986 | * user input by being clicked on or programatically by calling `nk_window_focus`. |
| 987 | * Windows by default are visible unless explicitly being defined with flag |
| 988 | * `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag |
| 989 | * `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling |
| 990 | * `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`. |
| 991 | * |
| 992 | * Usage |
| 993 | * ------------------- |
| 994 | * To create and keep a window you have to call one of the two `nk_begin_xxx` |
| 995 | * functions to start window declarations and `nk_end` at the end. Furthermore it |
| 996 | * is recommended to check the return value of `nk_begin_xxx` and only process |
| 997 | * widgets inside the window if the value is not 0. Either way you have to call |
| 998 | * `nk_end` at the end of window declarations. Furthmore do not attempt to |
| 999 | * nest `nk_begin_xxx` call which will hopefully result in an assert or if not |
| 1000 | * in a segmation fault. |
| 1001 | * |
| 1002 | * if (nk_begin_xxx(...) { |
| 1003 | * [... widgets ...] |
| 1004 | * } |
| 1005 | * nk_end(ctx); |
| 1006 | * |
| 1007 | * In the grand concept window and widget declarations need to occur after input |
| 1008 | * handling and before drawing to screen. Not doing so can results in higher |
| 1009 | * latency or at worst invalid behavior. Furthermore make sure that `nk_clear` |
| 1010 | * is called at the end of the frame. While nuklears default platform backends |
| 1011 | * already call `nk_clear` for you if you write your own backend not calling |
| 1012 | * `nk_clear` can cause asserts or even worse undefined behavior. |

| 1881 | /* Font handling in this library was designed to be quite customizable and lets |
| 1882 | you decide what you want to use and what you want to provide. There are three |
| 1883 | different ways to use the font atlas. The first two will use your font |
| 1884 | handling scheme and only requires essential data to run nuklear. The next |
| 1885 | slightly more advanced features is font handling with vertex buffer output. |
| 1886 | Finally the most complex API wise is using nuklears font baking API. |
| 1887 | |
| 1888 | 1.) Using your own implementation without vertex buffer output |
| 1889 | -------------------------------------------------------------- |
| 1890 | So first up the easiest way to do font handling is by just providing a |
| 1891 | `nk_user_font` struct which only requires the height in pixel of the used |
| 1892 | font and a callback to calculate the width of a string. This way of handling |
| 1893 | fonts is best fitted for using the normal draw shape command API where you |
| 1894 | do all the text drawing yourself and the library does not require any kind |
| 1895 | of deeper knowledge about which font handling mechanism you use. |
| 1896 | IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist |
| 1897 | over the complete life time! I know this sucks but it is currently the only |
| 1898 | way to switch between fonts. |
| 1899 | |
| 1900 | float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) |
| 1901 | { |
| 1902 | your_font_type *type = handle.ptr; |
| 1903 | float text_width = ...; |
| 1904 | return text_width; |
| 1905 | } |
| 1906 | |
| 1907 | struct nk_user_font font; |
| 1908 | font.userdata.ptr = &your_font_class_or_struct; |
| 1909 | font.height = your_font_height; |
| 1910 | font.width = your_text_width_calculation; |
| 1911 | |
| 1912 | struct nk_context ctx; |
| 1913 | nk_init_default(&ctx, &font); |
| 1914 | |
| 1915 | 2.) Using your own implementation with vertex buffer output |
| 1916 | -------------------------------------------------------------- |
| 1917 | While the first approach works fine if you don't want to use the optional |
| 1918 | vertex buffer output it is not enough if you do. To get font handling working |
| 1919 | for these cases you have to provide two additional parameters inside the |
| 1920 | `nk_user_font`. First a texture atlas handle used to draw text as subimages |
| 1921 | of a bigger font atlas texture and a callback to query a character's glyph |
| 1922 | information (offset, size, ...). So it is still possible to provide your own |
| 1923 | font and use the vertex buffer output. |
| 1924 | |
| 1925 | float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) |
| 1926 | { |
| 1927 | your_font_type *type = handle.ptr; |
| 1928 | float text_width = ...; |
| 1929 | return text_width; |
| 1930 | } |
| 1931 | void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint) |
| 1932 | { |
| 1933 | your_font_type *type = handle.ptr; |
| 1934 | glyph.width = ...; |
| 1935 | glyph.height = ...; |
| 1936 | glyph.xadvance = ...; |
| 1937 | glyph.uv[0].x = ...; |
| 1938 | glyph.uv[0].y = ...; |
| 1939 | glyph.uv[1].x = ...; |
| 1940 | glyph.uv[1].y = ...; |
| 1941 | glyph.offset.x = ...; |
| 1942 | glyph.offset.y = ...; |
| 1943 | } |
| 1944 | |
| 1945 | struct nk_user_font font; |
| 1946 | font.userdata.ptr = &your_font_class_or_struct; |
| 1947 | font.height = your_font_height; |
| 1948 | font.width = your_text_width_calculation; |
| 1949 | font.query = query_your_font_glyph; |
| 1950 | font.texture.id = your_font_texture; |
| 1951 | |
| 1952 | struct nk_context ctx; |
| 1953 | nk_init_default(&ctx, &font); |
| 1954 | |
| 1955 | 3.) Nuklear font baker |
| 1956 | ------------------------------------ |
| 1957 | The final approach if you do not have a font handling functionality or don't |
| 1958 | want to use it in this library is by using the optional font baker. |
| 1959 | The font baker API's can be used to create a font plus font atlas texture |
| 1960 | and can be used with or without the vertex buffer output. |
| 1961 | |
| 1962 | It still uses the `nk_user_font` struct and the two different approaches |
| 1963 | previously stated still work. The font baker is not located inside |
| 1964 | `nk_context` like all other systems since it can be understood as more of |
| 1965 | an extension to nuklear and does not really depend on any `nk_context` state. |
| 1966 | |
| 1967 | Font baker need to be initialized first by one of the nk_font_atlas_init_xxx |
| 1968 | functions. If you don't care about memory just call the default version |
| 1969 | `nk_font_atlas_init_default` which will allocate all memory from the standard library. |
| 1970 | If you want to control memory allocation but you don't care if the allocated |
| 1971 | memory is temporary and therefore can be freed directly after the baking process |
| 1972 | is over or permanent you can call `nk_font_atlas_init`. |
| 1973 | |
| 1974 | After successfull intializing the font baker you can add Truetype(.ttf) fonts from |
| 1975 | different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`. |
| 1976 | functions. Adding font will permanently store each font, font config and ttf memory block(!) |
| 1977 | inside the font atlas and allows to reuse the font atlas. If you don't want to reuse |
| 1978 | the font baker by for example adding additional fonts you can call |
| 1979 | `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end). |
| 1980 | |
| 1981 | As soon as you added all fonts you wanted you can now start the baking process |
| 1982 | for every selected glyphes to image by calling `nk_font_atlas_bake`. |
| 1983 | The baking process returns image memory, width and height which can be used to |
| 1984 | either create your own image object or upload it to any graphics library. |
| 1985 | No matter which case you finally have to call `nk_font_atlas_end` which |
| 1986 | will free all temporary memory including the font atlas image so make sure |
| 1987 | you created our texture beforehand. `nk_font_atlas_end` requires a handle |
| 1988 | to your font texture or object and optionally fills a `struct nk_draw_null_texture` |
| 1989 | which can be used for the optional vertex output. If you don't want it just |
| 1990 | set the argument to `NULL`. |
| 1991 | |
| 1992 | At this point you are done and if you don't want to reuse the font atlas you |
| 1993 | can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration |
| 1994 | memory. Finally if you don't use the font atlas and any of it's fonts anymore |
| 1995 | you need to call `nk_font_atlas_clear` to free all memory still being used. |
| 1996 | |
| 1997 | struct nk_font_atlas atlas; |
| 1998 | nk_font_atlas_init_default(&atlas); |
| 1999 | nk_font_atlas_begin(&atlas); |
| 2000 | nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0); |
| 2001 | nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0); |
| 2002 | const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32); |
| 2003 | nk_font_atlas_end(&atlas, nk_handle_id(texture), 0); |
| 2004 | |
| 2005 | struct nk_context ctx; |
| 2006 | nk_init_default(&ctx, &font->handle); |
| 2007 | while (1) { |
| 2008 | |
| 2009 | } |
| 2010 | nk_font_atlas_clear(&atlas); |
| 2011 | |
| 2012 | The font baker API is probably the most complex API inside this library and |
| 2013 | I would suggest reading some of my examples `example/` to get a grip on how |
| 2014 | to use the font atlas. There are a number of details I left out. For example |
| 2015 | how to merge fonts, configure a font with `nk_font_config` to use other languages, |
| 2016 | use another texture coodinate format and a lot more: |
| 2017 | |
| 2018 | struct nk_font_config cfg = nk_font_config(font_pixel_height); |
| 2019 | cfg.merge_mode = nk_false or nk_true; |
| 2020 | cfg.range = nk_font_korean_glyph_ranges(); |
| 2021 | cfg.coord_type = NK_COORD_PIXEL; |
| 2022 | nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg); |

| 2190 | * ===============================================================*/ |
| 2191 | /* A basic (double)-buffer with linear allocation and resetting as only |
| 2192 | freeing policy. The buffer's main purpose is to control all memory management |
| 2193 | inside the GUI toolkit and still leave memory control as much as possible in |
| 2194 | the hand of the user while also making sure the library is easy to use if |
| 2195 | not as much control is needed. |
| 2196 | In general all memory inside this library can be provided from the user in |
| 2197 | three different ways. |
| 2198 | |
| 2199 | The first way and the one providing most control is by just passing a fixed |
| 2200 | size memory block. In this case all control lies in the hand of the user |
| 2201 | since he can exactly control where the memory comes from and how much memory |
| 2202 | the library should consume. Of course using the fixed size API removes the |
| 2203 | ability to automatically resize a buffer if not enough memory is provided so |
| 2204 | you have to take over the resizing. While being a fixed sized buffer sounds |
| 2205 | quite limiting, it is very effective in this library since the actual memory |
| 2206 | consumption is quite stable and has a fixed upper bound for a lot of cases. |
| 2207 | |
| 2208 | If you don't want to think about how much memory the library should allocate |
| 2209 | at all time or have a very dynamic UI with unpredictable memory consumption |
| 2210 | habits but still want control over memory allocation you can use the dynamic |
| 2211 | allocator based API. The allocator consists of two callbacks for allocating |
| 2212 | and freeing memory and optional userdata so you can plugin your own allocator. |
| 2213 | |
| 2214 | The final and easiest way can be used by defining |
| 2215 | NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory |
| 2216 | allocation functions malloc and free and takes over complete control over |
| 2217 | memory in this library. |

| 2342 | /* Editing text in this library is handled by either `nk_edit_string` or |
| 2343 | * `nk_edit_buffer`. But like almost everything in this library there are multiple |
| 2344 | * ways of doing it and a balance between control and ease of use with memory |
| 2345 | * as well as functionality controlled by flags. |
| 2346 | * |
| 2347 | * This library generally allows three different levels of memory control: |
| 2348 | * First of is the most basic way of just providing a simple char array with |
| 2349 | * string length. This method is probably the easiest way of handling simple |
| 2350 | * user text input. Main upside is complete control over memory while the biggest |
| 2351 | * downside in comparsion with the other two approaches is missing undo/redo. |
| 2352 | * |
| 2353 | * For UIs that require undo/redo the second way was created. It is based on |
| 2354 | * a fixed size nk_text_edit struct, which has an internal undo/redo stack. |
| 2355 | * This is mainly useful if you want something more like a text editor but don't want |
| 2356 | * to have a dynamically growing buffer. |
| 2357 | * |
| 2358 | * The final way is using a dynamically growing nk_text_edit struct, which |
| 2359 | * has both a default version if you don't care where memory comes from and an |
| 2360 | * allocator version if you do. While the text editor is quite powerful for its |
| 2361 | * complexity I would not recommend editing gigabytes of data with it. |
| 2362 | * It is rather designed for uses cases which make sense for a GUI library not for |
| 2363 | * an full blown text editor. |

| 2457 | /* This library was designed to be render backend agnostic so it does |
| 2458 | not draw anything to screen. Instead all drawn shapes, widgets |
| 2459 | are made of, are buffered into memory and make up a command queue. |
| 2460 | Each frame therefore fills the command buffer with draw commands |
| 2461 | that then need to be executed by the user and his own render backend. |
| 2462 | After that the command buffer needs to be cleared and a new frame can be |
| 2463 | started. It is probably important to note that the command buffer is the main |
| 2464 | drawing API and the optional vertex buffer API only takes this format and |
| 2465 | converts it into a hardware accessible format. |
| 2466 | |
| 2467 | To use the command queue to draw your own widgets you can access the |
| 2468 | command buffer of each window by calling `nk_window_get_canvas` after |
| 2469 | previously having called `nk_begin`: |
| 2470 | |
| 2471 | void draw_red_rectangle_widget(struct nk_context *ctx) |
| 2472 | { |
| 2473 | struct nk_command_buffer *canvas; |
| 2474 | struct nk_input *input = &ctx->input; |
| 2475 | canvas = nk_window_get_canvas(ctx); |
| 2476 | |
| 2477 | struct nk_rect space; |
| 2478 | enum nk_widget_layout_states state; |
| 2479 | state = nk_widget(&space, ctx); |
| 2480 | if (!state) return; |
| 2481 | |
| 2482 | if (state != NK_WIDGET_ROM) |
| 2483 | update_your_widget_by_user_input(...); |
| 2484 | nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0)); |
| 2485 | } |
| 2486 | |
| 2487 | if (nk_begin(...)) { |
| 2488 | nk_layout_row_dynamic(ctx, 25, 1); |
| 2489 | draw_red_rectangle_widget(ctx); |
| 2490 | } |
| 2491 | nk_end(..) |
| 2492 | |
| 2493 | Important to know if you want to create your own widgets is the `nk_widget` |
| 2494 | call. It allocates space on the panel reserved for this widget to be used, |
| 2495 | but also returns the state of the widget space. If your widget is not seen and does |
| 2496 | not have to be updated it is '0' and you can just return. If it only has |
| 2497 | to be drawn the state will be `NK_WIDGET_ROM` otherwise you can do both |
| 2498 | update and draw your widget. The reason for seperating is to only draw and |
| 2499 | update what is actually neccessary which is crucial for performance. |

| 3918 | /* Since nuklear is supposed to work on all systems providing floating point |
| 3919 | math without any dependencies I also had to implement my own math functions |
| 3920 | for sqrt, sin and cos. Since the actual highly accurate implementations for |
| 3921 | the standard library functions are quite complex and I do not need high |
| 3922 | precision for my use cases I use approximations. |
| 3923 | |
| 3924 | Sqrt |
| 3925 | ---- |
| 3926 | For square root nuklear uses the famous fast inverse square root: |
| 3927 | https://en.wikipedia.org/wiki/Fast_inverse_square_root with |
| 3928 | slightly tweaked magic constant. While on todays hardware it is |
| 3929 | probably not faster it is still fast and accurate enough for |
| 3930 | nuklear's use cases. IMPORTANT: this requires float format IEEE 754 |
| 3931 | |
| 3932 | Sine/Cosine |
| 3933 | ----------- |
| 3934 | All constants inside both function are generated Remez's minimax |
| 3935 | approximations for value range 0...2*PI. The reason why I decided to |
| 3936 | approximate exactly that range is that nuklear only needs sine and |
| 3937 | cosine to generate circles which only requires that exact range. |
| 3938 | In addition I used Remez instead of Taylor for additional precision: |
| 3939 | www.lolengine.net/blog/2011/12/21/better-function-approximatations. |
| 3940 | |
| 3941 | The tool I used to generate constants for both sine and cosine |
| 3942 | (it can actually approximate a lot more functions) can be |
| 3943 | found here: www.lolengine.net/wiki/oss/lolremez |
